Katharine Johanesen

I am a "structural petrologist." I study ductilely deformed and metamorphosed rocks, especially those that form in high pressure or temperature settings. Field mapping, optical studies of rock microstructure, and thermobarometry are some of my primary tools. Findings on the scale of a microscope slide can have continent-sized implications!

My upper-level classes deal with the make-up and behavior of the solid part of the earth. We take field trips to localities all across the valley and ridge, to the New Jersey Highlands, the Newark Basin, the Adirondacks, and the Blue Ridge Mountains of Virginia and North Carolina.

I teach courses in Structural Geology, Mineralogy, Petrology, Field Methods, and Introductory Geology. My classes grapple with three-dimensional problems through multiple forms of visualization and interactive, hands-on models.


I study the interplay of deformation and metamorphism in rocks that come from deep inside the earth- sometimes along very complicated paths. I use a range of tools from GIS and field mapping techniques to optical and electron microscopy to solve tectonic questions.
